/*
 * The only purpose of this class is to hold onto an instance of
 * FtpClient to prevent the FtpClient from being garbage collected.
 * If the client gets collected it will close the command stream
 * which will cause the remote ftp daemon to close its outputstream
 * which will cause and EOF on this inputstream on our end.  
 *
 * The real answer is to re-architect all this stuff to not open an
 * ftp connection each time the user needs something from the remote
 * side.  The other correct thing it to totally ignore all the ftp
 * client stuff and just use the ftp proxy stuff in the CERN HTTP
 * server.
